1. Open the Expert screen of the motor of the individual slit blade.
  2. Click the << button to home the motor to the negative home position (e-mark). (It can be either the positive or negative e-marks to home, but we need to keep consistency. Here, we usually use the negative one.)
  3. Type “0” into the entry next to the << button, then click the “Set Dial” button below the entry. The Dial value will become 0.
  4. Find the X-ray beam position, set “Offset” so that the user value (Position RBV) is 0. The home procedure is done and the center and width should work automatically too.
